We're going to waste the next 5 years of prime Zeke, Amari, Jaylon, etc. on Jason Garrett.
The way the NFL is set up, you'll never have steak at every position. The league is built on parity and spreading the talent evenly across all teams; which places an even bigger emphasis on having a coach savvy and creative enough to mitigate his own team's shortcomings and exploit his opponents.
Garrett's simply not good enough to compete with top 10 coaches in the NFL, unfortunately for him (and Cowboys fans) those are the guys that you typically run into during the Divisional Rounds.
